Next version from Proof of Concept
Log from Strain Wave Gear with Timing Belts
I just want to get this in so we know it's been tried and seems to be an improvement over the version in the first video: The proof of concept constrained the timing belt along one edge to a circle. When the wave generator moves past a section of the...

Updated Drive System
Log from GoKart Tank
After much introspection, it looks like I am going to make some changes:3D Printed drive and idler sprockets at 17 teeth instead of 113D Printed road wheels (yes, printed), but also at 17 teeth, that will raise the chassis of the tank higher off the...

Two wrongs, make a more wrong.
Log from MPRT - Modified planetary robotics transmission
I both under-extruded and set values which were too large for backlash/clearance on my proof of concept. The under-extrusion was mostly on purpose. I didn't need this to handle any kind of load, and under-extrusion of gears produces perfect...

Log from Mood Gradient
After designing our main control box through the website "boxes.py," we assembled it through the laser-cutter computer, positioning each cut-out to make the most efficient cuts. We made sure to allow a bit of room between each piece, just in case the...

Figure Wheels
Log from 3D Print Babbage's Difference Engine No.2
Figure Wheels and Sector wheelsThe figure wheels are made from 40-teeth gear. Each figure wheel can store one digit (0 to 9). The nerigboring figure wheels are connected by a sector wheel, which is a section of a 40-teeth gear.The combination of...

Bipolar [Single/Micro-] Stepping Thoughts, ctd.
Log from CD/DVD mechanisms and cartesian thinggie[s?]
Alright, a tiny bit more research...This is a good resource:http://www.allaboutcircuits.com/textbook/alternating-current/chpt-13/stepper-motors/Here's a "Hybrid Stepper Motor" (simplified), (from that page):(simplified, further:)"Hybrid stepper motors"...

CNC cut test gear based on the parametric generator
Log from Strain Wave Gear with Timing Belts
I just wanted to say that I've tried cutting the HTD 5MM mount ring in my new CNC in 9mm plywood and it seems that when I place it over my first design revision there's a 1-2mm gap/play between the belt and gear. This isn't supposed to reflect at all...

3D Printing really large gears
Log from Creating an Autonomous Dinghy with ArduRover
I am in the experimentation stage. I have all the hardware together and just want to see this go.My current plan of record is the implementation of everything on my Dinghy instead of an RC boat. All I need is a very large servo motor (old windscreen...

Misadventures in warp zone
Log from Tardygrade
I'm planning to do some automated endurance testing of Tardygrade later in August. I want to find out if it can whitstand a few hundred hours of movement without breaking down. I'm actually more worried about the drive servo than the 3D printed mechanism,...

Measuring Magnetic Fields in a Volume
Log from low-field MRI
Let's have a look at the first test rig for measuring magnetic fields over a 3D volume.I confess that I've been thinking about this for a few weeks, and it's been a fun (and sometimes frustrating) design process. We'd like to accurately map the magnetic...

First Mock-up
Log from M.A.M.E. / Retrogaming Cabinet
I've found plenty of well documented cabinet builds online, but from my own experience at arcade machines, most of them are not quite tall enough for me. I often end up bowing down and having the marquee too close to my forehead. So I decided to start...

a different, different approach
Log from Locomatrix - 3D POV - a different approach
So watching the video from the last log, I noticed one mechanism, which seems perfect for my needs. The velocity is almost constant and so I took the time, made some screenshots and started inkscape. Since today is almost friday, 123d design wasn't able...

Insights from a Decade of Tipping Bucket Rain Gauge deployment
Log from The Cave Pearl Project
I know these janky installations will have the weather nerds out there inhaling through their teeth, but it’s worth noting that we made multiple attempts over the years to do things the ‘right way’ that just kept failing to go the distance. Even in a...

Axle Holes
Log from Go Kart Tank (formerly Half Track)
I found that I had to force the large threaded rod axles in very gingerly. I didn't want to wreck the wooden frame. I also realized I should cover the wooden frame in fiberglass when I was done. I made sure that the distance between the 2 rear axles...

Day/Night Detection
Log from Ghosty, the Thinking Nightlight
I need to use a photocell for day/night detection. Ghosty does not need to activate if I am standing in front of him brushing my teeth. My 3d printed structure is porous, but how much light gets through? Do I need a hole through the surface for a photocell?...
